31 July 2011 last Rigby BBC News updated at 07: 44 GMT by Caroline up to ? 70bn in the value of reserves in the rocks below South Wales can be of shale gas, research suggests shadow UK energy Minister Huw Irranca-Davies has the British Government develop a policy on shale gas required.

Potential multi-million pound reserves lie under in South Wales but his claimed Fracking called an extraction method causes pollution and could lead to earthquakes.

Ogmore MP says the gas can help deliver energy requirements but must be handled securely.

The Government says that attempts, for it must be drilling ecologically viable.

Mr Irranca-Davies Davies told BBC Wales country focus program, which he continues to pressure on the UK energy Minister, Charles Hendry on the subject.

It comes after research by exploration companies, which a possible ? 70bn of reserves in rocks found deep in South Wales and numerous planning applications submitted for test borings are carried out.

Mr Irranca-Davies said that the British Government must embed shale gas in its larger energy policy.

"The reason is that if you look at something else if it nuclear, is, whether it's oil industry if they wind and renewable energy or even tide fit them all within a proper coherent policy structure."

"With shale gas, we have the risk is it then bring captured us."

However, it is not against the exploitation of slate gas as a whole.

Health and safety

"Many people recognize that there may be potential for shale gas." "In particular, if on the decline in the North Sea gas and our increasing dependence on imports of gas-LNG look and elsewhere, from Russia, pipes made of Norway Rohrleitungen--could have the potential."

He added: "If shale gas, such as our accompanying transition to a low carbon future can and offer affordable gas cheap, as it has done in the United States, then great."

"But only if it is done safely when it serves no impact on the environment and the health and safety of persons in the areas will be also." "Why not the Government you this and decide, as do security, if at all?"

"We will continue to keep pushing because I do not want vollig-- shale gas excluded, even though I know there are some people who would want to see it completely prohibited."

"But I do not agree with them because I think that we need to assess their potential and their risks adequately."

The Department of energy and climate change said that companies need to go to win before all Fracking takes place through a variety of reviews including planning permission.

Earlier this month national level guidelines to promote gas shale Vale of Glamorgan Council leader, Gordon Kemp, called for.

The Welsh Government has also said that it is working with UK Minister to set up it would welcome a political framework.

A spokesman said it "British Government work with decentralised administrations a introduce overall concept for shale gas would welcome." "But the case for a moratorium is Westminster."
